Problem space in UIWebView

In practice I have a button that sends the request to a URL to a UIWebView eg: tel:124324 4563, but unfortunately it does not load the page because there is a space. How do I remove the space? as happens in Mobile Safari that I开发者_开发技巧 replace it with %20?

Thanks

The easiest way is:

[string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]

As documented here.

- (NSString *)stringByAddingPercentEscapesUsingEncoding:(NSStringEncoding)encoding

You can use [myString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
